While on a business trip away from home noticed the heater stopped blowing warm air. A few minutes later engine temperature spiked but then returned to normal. 50 miles later heater started working again. Took the car to a local mechanic and discovered transmission cooler within the radiator had failed, allowing the radiator coolant to mix with the transmission fluid. Paid for the replacement of the radiator/transmission cooler, system flush. Had the system flushed again 1 week after radiator replacement. Transmission now acting erratically, particular when shifting between 3rd and 4th gear. Initial assessments by mechanic suggests transmission and transmission computer require replacement. Cost of replacement exceeds the value of car even though the rest of the car is in excellent condition.

TL-the contact owns a 2006 Nissan Xterra. The contact stated that while driving approximately 65 mph, the engine stalled without warning. The vehicle failed to restart and was coasted to a safe location. The vehicle was towed to an authorized dealer where the ECM relay was replaced. In 2011, the vehicle was repaired under NHTSA campaign id number 10V517000 (engine and engine cooling). The contact had not previously experienced a failure at the time the vehicle was repaired under the recall. The manufacturer was notified of the problem. The approximate failure mileage was 68,000. The VIN was unavailable. Kmj

Nissan will not step up and fix their mistake, our car is at 87000 miles and the coolant is leaking into the transmission due to how Nissan configured their system from the years of 2006 - 2009. When I spoke with william at Nissan Consumer Affairs he intimated that Nissan is not aware of this being a major issue, but interestingly enough stopped using this configuration in 2010. They claim that it will not happen to every Nissan, we need more consumers to come forward, so that this will become a "recall". the system is faulty it may not happen at 80,000 / 90,000 / 100,000, but count on it happening at some point. This is a very expensive repair. If Nissan had communicated to us that the warranty covering this transmission failure was extended to 80,000 but of course why would they admit to a faulty system, and let their valued customers know. Simple they do not value their customers, they lost this group. Way to go Nissan, somewhere down the line this will hurt you. Signed-disgusted

Started over a year ago that while driving the motor would just stop running, would have to coast to the side if the road without power steering or brakes. I took it into the shop and they couldn't find out the problem. Now that my transmission is starting to shake and make noise, I took it to the dealer. They told me that my radiator is making into the transmission and that makes the motor quit and loss of power. I am informed that I need a new radiator and transmission. Looking online I see that there are a lot of people with this sane safety issue and that there is no recall. I think that there should be a recall because it's safety alone! I almost hit a car and a pedestrian while trying to steer off the road and stop. Please help with a recall!! thanks josh

The transmission started to slip, turns out the atf was contaminated by the radiator failing and leaking coolant into the transmission. This was determined by the dealer and of course it was out of warranty. I replaced the radiator and the transmission is being worked on by a transmission shop to the tune of several thousand dollars. The contamination ruined at least all clutch plates, the bands, and the torque converter.

Transmission went out. While driving on highway, rpms went up and car would not move. Diagnosis was new transmission and radiator. Seems to be a problem with 2006 Nissan Xterras with low mileage.

The transmission in my vehicle began to slip. I had amco and Nissan investigate the problem and both companies determined that the coolant from the radiator had leaked into the transmission. This caused the vehicle to become inoperable.

Premature wear of the secondary timing chain guides could lead to engine failure durring use and incurs expensive repairs well before the end of life of the timing chains which is much longer than the useable life of a belt.

Driving South on the Florida turnpike, our Nissan X-terra would not change speed at 40 miles per hour and it appeared that the transmission could not change. The slip indicator light went on. This situation happened approximately three times, after each incident we had to stop on the side of the highway. Finally after the third attempt the vehicle picked up speed. When we got home, I checked the transmission fluid and it had what appeared to be water. I checked the radiator cap, and instead of liquid the mixture seemed to be a creme paste, like it had oil. Searching in google, I found that there was a lawsuit brought again Nissan for this defect. However today at bill seidle's Nissan in miami, I was told that there is a co-payment of $2,500. This is outrageous, since the problem was created by Nissan and not by the owner of the vehicle.

I really do not know where to begin. My truck would not start 8/26/13. I learned that the dreaded radiator coolant leak had finally destroyed my transmission computer system and transmission. I first learned that this could become a problem in February of 2011 when my vehicle was at about 96,300 miles. The Nissan dealership gave me a number to call, I did and was told at that time that I could pay $6000 out of pocket and possibly be reimbursed later as my vehicle VIN was not in the current list of vehicles being offered the "special warranty coverage". I was given a case number and told I would be mailed information about all future matters regarding this problem. I did not have $6000 then, I do not have $3000 now. That is the amount of the deductible the Nissan dealer says I would be responsible for paying if Nissan honors the time I initially reported this problem to them. I need some help. My husband is active duty navy and I kept this vehicle serviced and did everything I was supposed to do to make sure this vehicle stayed in great condition and now I have a vehicle that is no longer working. I hope you can help us.

Xterra 6-cyl

  • 99,950 miles
On December 06, 2013, while merging onto the highway, my gray in color, 2006 Nissan Xterra, completely lost all motive power & failed to shift gears, simply revving out in 2nd gear. It should be noted, my 2006 Nissan Xterra is the 4X4, automatic transmission & had around 99,950 miles at the time. The incident put myself, my wife, and my eight month old baby girl in danger due to the fact we had no where to exit the highway & were quickly slowing down in traffic. This incident almost caused an accident because I was unable to accelerate to get out of the way of the faster highway traffic. It has since come to my attention that Nissan is aware of this issue and that it is caused by the radiator leaking coolant into the transmission causing the transmission fluid to mix with the radiator fluid, effectively destroying the transmission. I was able to slowly work the rpms up & get the transmission to shift up a few gears so we could make it off the highway. I then contacted my local Nissan dealer who advised that Nissan was aware of the issues and have extended the warranty to 100,000 mi. He informed me that to replace the transmission & the radiator it would cost approximately $7000, however, if I was under 100,000 mi, I would only have to pay a $3,000 deductible. Because I had passed the 100,000 mile mark by driving my vehicle back home, I was no longer eligible for this extended warranty. I've owned my Nissan Xterra for over 6 years & have made sure to stay current on all the routine maintenance. The fact that Nissan is not only aware of these issues (which have allegedly affected thousands of Nissan owners), but also that they have failed to take any corrective action, is simply unacceptable & also downright dangerous. It is one thing for Nissan to not stand behind their product, but it is wrong for them to knowingly allow their product to put people's lives in danger.

I was coasting on the freeway at around 50 miles, was in low RPM about 2500. I hit the gas to change lanes and as soon as I did, I have no power to the back wheels. My engine RPM shot up and felt as if I was in the neutral. Eased off immediately and tried gassing it very lightly. I was able to make it off the freeway; however, I could not gas it past the 2500rpms. Very scary on the freeway, lucky I have great reflexes to avoid an accident. Took it into the shop and verified it is a leakage from the radiator to transmission problem.

My 2006 Nissan Xterra's transmission has been significantly damaged due to the issue of contaminated transmission fluid / radiator fluid. It started to exhibit symptoms shortly after reaching 100,000 miles, which is just out of reach of the extended warranty.

Noticed a coolant smell, loss in power and rumble vibration type feeling coming from the center of the vehicle. Went away and came back. Researched some Xterra forums and came across the radiator issue leaking coolant into transmission. I opened cap, saw a reddish river. Drained a 1/4 cup and its the strawberry color showing the mix.

Xterra 6-cyl

  • 96,500 miles
I had been noticing a whining noise associated with transmission 'flare' on acceleration for some time, but only in March 2013 was it diagnosed at 96K miles by the dealership as faulty timing chain guides, a known problem with the 4 L engine. The dealer said the faulty parts needed to be replaced soon. I contacted Nissan usa Consumer Affairs about having Nissan partially cover the cost of replacing the faulty parts. Despite having the dealership's original report and estimate, Nissan's regional rep insisted that the dealership had to reconfirm the diagnosis, which was done. The rep then refused to return my calls, and did not respond to dealership queries about the repairs either. The engine noise was getting worse, and fearing a catastrophic engine failure, I had the dealer repair the vehicle. The dealer said the timing chain was slapping and about to fail. The dealership urged me to report the problem to appropriate federal, local and Nissan officials because the problem is potentially very dangerous.

Check engine light came on and stayed on. Had diagnostics and found catalytic converter not to be working properly. Replaced catalytic converter on 29 Nov 2012. Again on May 2013 check engine light came back on and again it was the catalytic converter. Had to have it replaced again. Total cost of both replacements was in excess of $1900. Contacted Nissan and they would not stand behind their product, said that warranty had expired. Had converter replaced at Nissan dealer the first time.
